MECHANISM OF TETRAHYDROFURAN RINGOPENING POLYMERIZATION INITIATED BY BORON TRIFLUORIDE

MECHANISM OF TETRAHYDROFURAN RINGOPENING POLYMERIZATION INITIATED BY BORON TRIFLUORIDE

The commercial hydroxyl group terminated polytetramethylene glycol （PTMG）is prepared by the cationic ring-opening polymerization of tetrahydrofuran （THF）by using a strong protonic acid initiator system such as fuming sulfuric acid and others. There has been considerable interest in the low-corrosive...

Zusammenfassung:The commercial hydroxyl group terminated polytetramethylene glycol （PTMG）is prepared by the cationic ring-opening polymerization of tetrahydrofuran （THF）by using a strong protonic acid initiator system such as fuming sulfuric acid and others. There has been considerable interest in the low-corrosive BF3 initiator system. However, the low
